Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio / video reproducing system suitable for application to a karaoke reproducing apparatus using a digital data recording disk called CD (compact disk).

[0002]

2. Description of the Related Art Conventionally, a karaoke reproducing apparatus (that is, an accompaniment sound of a song is reproduced and a sound input from a microphone is mixed by using a compact digital data recording disk having a diameter of about 12 cm, which is called a CD (compact disk). Various devices are being developed. In this case, in the case of what is usually called a CD, only a maximum of about 74 minutes of audio data is recorded as main digital data on one disc, but in a karaoke reproducing device, images such as lyrics are reproduced. It is more convenient to display it according to the voice. Therefore, the CD used for karaoke
In some cases, there is an additional recording area called a subcode in which video data of a still image for displaying lyrics is recorded.

[0003]

By the way, since a still image such as lyrics is inferior to a displayed image in this way, a lyrics image reproduced from such a disc is a moving image image reproduced from a video disc or the like. What has been developed has been developed so that a good moving image can be displayed on the screen of a monitor receiver that superimposes on a signal and displays lyrics. In this case, a plurality of background images are prepared on the video disc side, and one of the background images is selected and reproduced in association with the reproduction of the sound from the CD.

In some cases, only the sound may be reproduced from the CD, and only the image reproduced from the video disc may be displayed on the screen of the monitor receiver in synchronization with the reproduction of the sound.

However, the operation of selecting the background image in this way is inconvenient and time-consuming. That is, when the player of the CD performs the operation of selecting the music to be played from the CD, the background image also needs to be selected at the same time, and the double selection operation is required, and the operation is complicated and difficult to understand. There was an inconvenience.

Further, in such a case, it is difficult to know what kind of background image is selected. That is, conventionally, there is no one that actively displays the type of the selected background image at the stage of performing the music selection operation, and actually starts the reproduction of the music and displays it on the monitor receiver. I couldn't understand what kind of background image would be displayed without seeing the image.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to easily select a good background image in a reproducing system of this type.

[0008]

According to the present invention, for example, as shown in FIG. 1, reproducing means 12 for reproducing audio data from a recording medium 11 in which plural units of audio data are recorded with individual numbers. The control means 21 for controlling the individual number of the audio data reproduced by the reproducing means 12, the video signal source 5 capable of selecting the output video based on the control by the control means 21, and the input operation of the individual number are performed. Go and control means 2
1 is provided with a number input means 1 for instructing a number to be reproduced,
When the number input means 1 inputs a number obtained by adding a constant value to the individual number, the control means 21 causes the reproducing means 12 to reproduce the voice data of the individual number obtained by subtracting the constant value from the input number. At the same time, as the image output from the image signal source 5, an image different from that when inputting without adding a constant value is selected.

Further, according to the present invention, for example, as shown in FIG.
Reproducing means 12 for reproducing the audio data from the recording medium 11 in which a plurality of units of audio data are individually recorded and recorded, and control means 21 for controlling the individual number of the audio data reproduced by the reproducing means 12. A video signal source 5 capable of selecting an output video based on the control by the control means 21.
And reservation display screen creating means 41 to 45 for creating video data of a reservation display screen for displaying information on audio data reserved to be reproduced from the reproducing means 12, and the control means 21 controls the video signal source 5 to operate. The display mode of the reservation display screen created by the reservation display screen creating means 41 to 45 is changed according to the type of the output video.

Further, in each case, the image output from the image signal source 5 is combined so as to be displayed on the background of the image obtained by reproducing from the recording medium 11.

Further, as a change of the display mode on the reservation display screen, the display color of the background is changed.

[0012]

According to the present invention, when the number input means only inputs the number obtained by adding a certain value to the individual number of the audio data to be reproduced, and the input is made without adding the certain value. Video data different from that can be output, and the video type can be selected only by inputting a number.
Therefore, for example, by applying it to a karaoke system that reproduces audio and video from different media, it is possible to select the video that matches the audio that is reproduced by simply operating the number of the song that is to be reproduced. It is not necessary to select with, and operability is improved.

Further, according to the present invention, the display mode of the reservation display screen created by the reservation display screen creating means is changed in accordance with the type of the video output from the video signal source, so that the reservation display is performed. The selection state of the image can be grasped from the display mode of the screen, and the usability is improved.
